Granted, Green Monday is not as well known as other big sales days. And that's a large reason why it may not exist long beyond 2017. "With the two-day shipping guarantee that comes with an Amazon Prime membership," reports BI, "and Walmart's two-day shipping offering with any $35 purchase, there may not be a compelling reason for last-minute shoppers to click check-out on Monday."
Of course, many of us wait until there is little time left before finishing our Christmas shopping. And if you think about it, that alone is reason enough for Green Monday to live on and prosper.
